Question

我是XSLT的新手，我发现很难弄清楚如何计算从两个元素（价格和数量）生成的所有小计。

任何帮助表示感谢（包括指出我迄今为止所做的比特效率低下的代码，我是新手，还在学习，所以我需要帮助）

Answer 1

请试试这个：

<tr>
    <td colspan="3" align="right"><b>Grand-total</b></td>
    <td>
        <xsl:value-of select="sum(for $item in (/Items/Item) return $item/Quantity * $item/Price)" />
    </td>
</tr>

它使用for expression计算每个小计，并使用sum函数来计算总计。
